Objective: System-level safety measures do not exist to ensure that patients with iron deficiency anaemia (IDA) undergo proper diagnostic evaluations. We sought to determine if a set of EHR (electronic health record) tools and an expedited referral workflow increase short-term completion of bidirectional endoscopy in higher risk patients with IDA.
Materials and methods: We conducted a pragmatic, cluster-randomised trial randomised by primary care physician (PCP) that included 16 PCPs and 316 patients with IDA. Physicians were randomised to intervention or control groups. Intervention components included a patient registry visible within the EHR, point-of-care alert and expedited diagnostic evaluation workflow for IDA. Outcomes were assessed at 120 days. The primary outcome was completion of bidirectional endoscopy. Secondary outcomes were any endoscopy completed or scheduled, gastroenterology consultation completed, and gastroenterology referral or endoscopy ordered or completed.
Results: There were no differences in the primary or secondary outcomes. At 120 days, the primary outcome had occurred for 7 (4%) of the intervention group and 5 (3.5%) of the control group. For the three secondary outcomes, rates were 15 (8.6%), 12 (6.9%) and 39 (22.4%) for the immediate intervention group and 10 (7.0%), 9 (6.3%) and 25 (17.6%) for the control group, respectively, p>0.2. Lack of physician time to use the registry tools was identified as a barrier.
Discussion and conclusion: Providing PCPs with lists of patients with IDA and a pathway for expedited evaluation did not increase rates of completing endoscopic evaluation in the short term.
